NEW YORK: The United States set a one-day record with over 1 million coronavirus diagnostic tests being performed, but the country needs 6 million to 10 million a day to bring outbreaks under control, according to various experts.

The country performed 1,061,411 tests on Saturday, according to data from The Covid Tracking Project, a volunteer-run effort to track the outbreak.

The record comes after testing has fallen for several weeks.

The United States tested on average 650,000 people a day in the week ended Sept. 13, down from a peak in late July of over 800,000 people a day.

Since the start of the pandemic, testing shortages have hampered efforts to curb the spread of the virus.

At one point during the summer, Houston residents lined up in cars and waited hours for tests, even sleeping in their vehicles overnight. Miami saw similar lines. Once tested, people may have to wait up to two weeks to learn if they have the virus, which has killed nearly 200,000 Americans and infected more than 6.7 million. Such delays defeat the purpose of trying to prevent further infections.
